Define/Explain the following terms:
$(i)$ Leaf-like stem (Phylloclade)
$(ii)$ Stolon

(N/A) $(i)$ In plants of arid regions,leaves are often reduced or shed to control transpiration. In the absence of leaves,the stem becomes green,fleshy,and flattened to perform photosynthesis. This modified photosynthetic stem is called a phylloclade (e.g.,Opuntia).
$(ii)$ $A$ stolon is a slender,horizontal branch that arises from the base of the main plant axis. It grows above the ground and produces new daughter plants from buds located at its tips or nodes upon touching the soil (e.g.,Nephrolepis,strawberry).
